Since the emergence of Light Emitting Diode (Light Emitting Diode), people have been striving to achieve solid-state light sources. With the continuous progress of LED manufacturing technology and the development and application of new materials (nitride crystals and phosphors), LED semiconductor solids The performance of the light source continues to improve and enters the practical stage.

The emergence of white LEDs has enabled high-brightness LED applications to enter the high-efficiency lighting source market. The light-emitting diode is a semiconductor component with a long life; the conversion from electricity to light has high efficiency and low power consumption; at the same time, the light-emitting diode component is a very small light-emitting source, which can cooperate with the miniaturization of various application equipment. Compared with general lighting, white light-emitting diodes save power (the power consumption is 1/8 to 1/10 that of general bulbs and 1/2 of fluorescent lamps.

In addition, LED lighting has a long life (up to 100,000 hours or more), low heat generation, (less heat radiation), fast response speed (high-frequency operation possible), and it is safe and environmentally friendly for waste disposal (no mercury pollution).

As LED lighting has many of the above advantages, it is expected to replace tungsten lamps and mercury lamps in the 21st century and become a new lighting source with both power saving and environmental protection. Therefore, it is known as the rising star of "green lighting source".

Capacity and hardware design of solar street lights

The main purpose of the capacity design of the solar street light system is to calculate the capacity of the solar cell components and storage batteries required for the reliable operation of the system throughout the year. At the same time, we must pay attention to the relationship between the maximum reliability of the system work and the system cost, and minimize the cost on the basis of meeting the maximum reliability of the system work.

The main purpose of the hardware design of the solar street light system is to select the appropriate hardware equipment according to the actual situation, including the selection of solar cell components, bracket design, cable selection, control system design, lightning protection design, lighting and illumination design, etc. The software and hardware aspects of the system need to be considered comprehensively when designing the system.

Before proceeding with the design of the solar street light system, it is necessary to understand the basic data required for calculation and selection: the geographical location of the solar street light system installation, including location, latitude, longitude and altitude; meteorological data of the area, etc.
